Smart phones are the most common communication devices we use today, replacing landline phones and becoming fashionable communication and entertainment tools.Cell phone jammer is installed in the school or college and other trouble-free areas. But what about the device that interferes with the phone? The jamming devices prevent the phone from receiving signals from the base station. Even if it sounds like a complicated process, it's not complicated to set up your own mobile phone.

Understand the principles of operation. These phone jammers work on the GSM 800 frequency, because most phones use their functions. The selected voltage control oscillator is a very effective remote oscillator, but without good rf test equipment, it is difficult for beginners to establish.
As a source of noise, you can use the 45mhz clock oscillator to drive the local oscillator connector on the mini circuit mixer. For local oscillator signals, there is also a network with the same resistor. It is used to balance the resistance of clock oscillator and mixer connection.
The high frequency input (mixer's connector) connects to the first 800MHz mobile antenna, and the high frequency output is sent to the microcircuit amplifier. The amplifier increases the output power to 15-16dbm. The amplified signal is then sent to the second mobile phone antenna.

All GSM 800 phones will transmit and receive frequencies at 45 MHz. So when the phone tries to make a phone call, it is blocked by its own signal! Isn't that cool? If the chatter on the phone annoys you - turn on your signal jammer, the gangster hears his voice on his cell phone.

If you are a driver or a traveler, you can use it as a GPS jammer. Do you worry if there are some bad guys who can track your location if you and your family have a trip? Bad people can get angry, want to steal your luggage, to get wealth, when you go to a desolate place. They will always wait for the right time to take action. This is not only for your property, but also for life. So, GPS jammers can even save your life one day!

Here you can ask how it achieves this versatility. For example, if you can lock a phone signal without being affected by a GPS or WiFI signal. We want to tell you that the device is equipped with adjustable buttons, so you can choose the range of frequencies. That is, when you shut down other frequencies, it can only call the intruder or the GPS.

Moreover, all frequencies can work simultaneously. In addition, the blockage of this high performance fault can be as long as 40 meters, or it can be adjusted according to the need of adjustable buttons. What's more, the car charger with these 3G 4G mobile phone and car accessories? GPS WiFi jammer can be easily used in cars. In addition, due to the high quality heat dissipation system with built-in cooling fan, the device can achieve 24/7 work.

Many people may wonder if cell phone interference is harmful to our health because they play a variety of frequencies that are dangerous to us. Now, more and more people are buying mobile phone smears and other blocking devices. From this point of view, we already know the answer, because the people of the eyes are very demanding. We can fully understand them, because we know how important it is to protect your privacy, and because most of the government is doing all he can monitor all of us, we have no choice, can only buy the predicament, to protect our privacy,

However, we must clarify this in technical terms. If there is a health problem, the phone jammer has passed all safety and health tests, and because of this fact, you can make sure you buy and use it. If you remember, when the phone was first introduced to the company, the same health concerns were worrying. But after testing, the results were the same - no harm.

In addition from the working principle of jammer Send you should keep in mind that phone interference with the normal work of the mobile phones of the same frequency interference, that is to say, our jammer is similar to our mobile phones. And today, is there any device that allows us to maintain a long phone call? What devices are more popular than mobile phones? So, when we talk about mobile jammer damage is the same - they are and the phone itself, wi-fi signal blocking the same thing, they are like wi-fi hotspots, the hot spot is dangerous? One thing you should know is that radio signals and light, sound waves and gravity follow the same inverse law, that is, the distance is doubled, and the energy is reduced to a quarter. In other words, the signal intensity decreases with increasing distance. The most interesting fact is that people worry that GPS/GLONASS drone jammer devices are harmful, but they don't even know that the signals from these positioning systems surround them every day.

So we want to remind you again that it's important to know how often you want to play. You can find any information about cell phone interceptors and other locking devices on the Internet and on special websites. One thing is for sure - the technology will not stop developing.

With parity, hot spots and a host of mobile devices at home, it's not that easy today. Almost every 13-year-old has a small computer hidden in the back pocket of his skinny jeans. And parents who would never allow their children to have their own TV in the room, have them chat for hours on the bed WhatsApp, post Instagram, play games, watch Youtube video, work...
Teachers think all of their students have smartphones - if not, this is a problem: classroom chat on Whatsapp, which includes teachers, is an information channel; A child who does not have a cell phone or is not allowed to join Whatsapp is called a "victim" by classmates.

Mobile phone jammers are used in the United States

As long as there is a jammer, what the americans call "cell phone jammers." In America it is illegal (a fine of ,000), but in this country, the culture of peace, the man of justice, is very firm, and they have allowed them to come from abroad. That's what the New York times recently revealed in an interview... Those who sell from London or mumbai.

Portable Multi-functional Jammers for Phone GPS WIFI or Video

The principle is simple: cell phone jammer sends a strong enough signal to prevent adjacent phones from communicating with the wired antenna. Children are a few metres (starting at ), and some companies buy fixed rooms, rooms, and buildings for a fixed fee (from ,000 to ,000). One of the users who was tired of being interrupted during the treatment, a restaurant manager who couldn't stand to see the call was constantly distracted by his employees and teachers, and they made sure that they didn't get interfered by an outside disturbance. The incidental victims (who have not done wrong) can be very many. So what is the hardest thing to bear, if you are in public and insist on his nonsense or a man to restore order to someone who doesn't know, without taking into account the rights of others? Some of the condemnations have been praised by others, and the Los Angeles times has become a "national obsession" in the media debate camera wi-fi signal blocker and social network. Is this man a hero or a liar? Internet users want to know when others claim the device is useful in classrooms or theaters.

The media debate is enough to make the FCC very serious about this practice illegal. For the fact of the author, on public transportation to use the device is quite legislation "grey area". To NBC, he explained that he knew, before confirm your own mistakes, to cut off the television or radio signals is illegal, not to interrupt the GSM signal. In fact, the FCC is clear: using a GSM scrambler is a violation of federal law. Also, increased commissions, their sales are banned in the United States. The FCC says, "these devices are a critical risk to public safety, and it may stop you from calling 911 and emergency Numbers.

As a result, young people in Philadelphia face heavy economic penalties, seizing illegal goods and criminal sanctions until they are jailed. "According to adlane black's authorization of cell phones in the prison, many restrictions have been placed on the need to maintain familiaux- allowing prisoners not to break completely with their external environment, thus better prepared to return to society to prevent the risk of recurrence. In a briefing, Jacques dicker, the student's lawyer, made interesting recommendations to make this possible, to authorize, to respond to the criticism of the European court of human rights. Thus, in its April 25, 2016 decision, the European court of justice argued that the violation of the convention was a violation of article 3 of the convention, which, in conjunction with the length of the remaining cells and the remnants of the old building, was justified by the European commission on human rights, which proved that the conviction of France was justified.

The European court can also make a ruling in the future of the treaty 8 to protect private and domestic life, and to make a ruling on the potential detention conditions: the isolation and the possibility of a detainee to raise a cell phone to a man who was deprived of his freedom. The freedom of freedom jean-marie Delarue, the director of the disenfranchised site of a cell phone in a prison cell that reflects the power of leadership, has to be at a certain level of high power jammer and effective decision-making. But the general auditor has only the recommended powers. The target of cell phone authorization is compatible with criminal policy. Therefore, the political debate involving the attorney general is necessary. It will also provide the opportunity to raise public awareness of the French detention conditions. In addition, the mobile phone's framework authorization will enhance the surveillance effectiveness during detention. The 400 guards and security doors that have been installed in recent years look poor. The imagination of prisoners and their accomplices is fraudulently fertilize through laptop computers. In the end, the watchdog spends a lot of time tracking down poorly performing phones (900 phones per year in Baumettes), but could be jailed for months.

Over the years, the prison administration has spent millions of euros in drug seizures. His absolute weapon: hundreds of interferers. So, do they work?

To check whether the jammer work, just look at social network, including a periscope application, allows you to shoot and on-site dialogue with anyone. This week, for example, a prisoner was filming himself from his cell. He answered the user's questions by applying. After about ten minutes of communication, there were more than a thousand people.

Scrambler is valid on 2G network

Why don't you work with a telephone jammer? Since 2003, French prison facilities have been fully equipped, with 804 installed. But according to the prison monitor, StephaneBarraut, it doesn't seem to be. The problem is that the GPS jammer, which is equipped with a French prison, is a blur of 2G networks, but not 4G.

But what does the justice department do? Jean-jacques Urvoas doesn't want to answer our questions. But he assured him that he had taken the problem. Three million euros will be invested in high-tech jammers. At the same time, in the afternoon, the same detainee is connected again.

Last year, the prison checked 31,000 cell phones, and apparently there was a surplus.

Wireless alarm has the advantages of small area, easy installation and use. Its special accessories and the connection between the alarm center through a system of medium type GSM radio waves to operate. Today, offenders use jammers, called jammers, to neutralize this type of alarm.

What is interference

"Jammer" is a GSM wave and radio jammer specially used by professional thieves. Interference principle including the launch of the signal superposition equipment to such as the center of the telephone operator communication antenna signal, also includes the central alarm and transmission between the parts of the system. However, GSM jammer cannot block the use of between 433 and 868 MHZ radio frequency band signal alarm center. Therefore, there are models of radio "jammers" that inhibit these frequencies. The sale and purchase of "interference" is highly regulated in France. In principle only cinemas and prisons are allowed to use it. However, jammers can be easily traded on the Internet.

How does the jammer neutralize the wireless alarm?

The interference source blocks the transmission of GSM or radio waves. GSM jammers prevent send alerts to cell phones, and radio interference device can prevent the detector for communication between control panel and alarm system. Disruption is actually some of the flaws in wireless alerts. In fact, this communication can only be communicated with a radio frequency band with a detector and a GSM band with a central operator. Therefore, if these links are cut off, the alarm will not jump. To do this, burglars use the "interference" of both GSM and radio waves.

How to prevent interference?

When purchasing the alarm, it is important to know that some models have functions to prevent wave interference, including interference detectors. If the GSM signal drops, the detectors trigger the alarm. When using portable cell phone jammer to disable the control panel, the alarm will explain the communication does not exist, and its components to stop and an alarm via text message or phone. You can also choose to send two different frequency double frequency alerts simultaneously. In addition, the market also provides the interference model of the detectors. They have advantages that are independent of the alarm system. But, must pay attention to really neutralize a alarm system, alarm must make alarm system at the same time all the radio channel is invalid. In order to really prevent invasion, you should not communicate with others, installed in the house type of alarm clock.

This week marks the launch of the latest DroneShield product, the DroneGun portable rifle jammer, which works independently or in conjunction with DroneShield's drone detection technology to locate and eliminate potential airborne threats.

Drone sales are expected to grow exponentially in the near future, and the number and severity of the daily drone incidents continues to increase, with DroneShield launching DroneGun to deal with the malicious use of consumers and commercial drones, which would require effective countermeasures against drone intrusions. DroneShield aims to help public and private sector customers take active measures in the context of the law to guard against airborne security, security and privacy threats.

How do drone jammers work?

The jammer is designed to destroy the drone by exploding electromagnetic noise in the drone radio frequency, the drone operation and transmission of video, and the power level is sufficient to overwhelm any effective communication between the uav and the pilot. Usually, this is 2.4 Ghz or 5.8 Ghz (" RF - jamming "), which is "unallocated" public frequency, which means that the drone interference does not interfere with manned aircraft, mobile phone, public broadcasting or other specialized radio spectrum. In addition to RF interference, if the customer is legal (depending on jurisdiction, which may include military, law enforcement, first responders and private users), it can also use GPS jammer because a large number of drones rely on GPS to balance the wind, or between predetermined routes.

When a drone is hit by a jamming signal, the drone usually returns to the origin (unless the GPS is also stuck), allowing the user to track the drone to the pilot. Sometimes, unmanned aerial vehicle (uav) may occur even vertical drop, and is in good condition in site, this provides a forensic investigation of choice. Landing on site is also the general response of drones, when rf and GPS are stuck simultaneously.

Jammers can be effective against drones a few kilometers away. In general, compared with unmanned pilots, the operation of the jammer and unmanned aerial vehicles (uavs) and the distance between the drone jammer. The farther the drone on the plane, the better the interference. The typical effective distraction is a cone of about 15 to 30 degrees, protruding from the gun (which is also affected by the power of RF band and interference).
